$B_{s,d}^0\to {\ell }^{+}{\ell }^{-}$ Decays in Two-Higgs Doublet Models

Abstract

We study the rare leptonic decays $B_{s,d}^0\to {\ell }^{+}{\ell }^{-}$ within the general framework of the aligned two-Higgs doublet model. A complete one-loop calculation of the relevant short-distance Wilson coefficients is presented, with a detailed technical summary of the results. The phenomenological constraints imposed by present data on the model parameters are also investigated.
